Following are digitized figures from the text for use in compounding

Finite height

$\beta$ for finite height effects can be found using the following plot. Note that the finite height plot also includes effects of finite width for a centered crack. If your crack is not centered, you will need to subtract this effect.

Offset internal crack

$\beta$ for offset internal cracks can be found using the following plot. Note that there are two $\beta$ values, one near the edge, (Tip A), and the other away from the edge (Tip B).

You may have to refer to this chart twice to consider the effects of two edges.

Cracks near a hole

For cracks near a hole, the following two charts can be used to find $\beta$. Note that you will find one $\beta$ per hole per crack tip. Tip A refers to the tip farthest from the hole, Tip B is the tip closest to the hole
